Daisy Chaining
To control even more computers, up to 31 additional KH2508A / KH2516A
KVM switches can be daisy chained from the original KH2508
A or KH2516A.
As many as 512 computers can be controlled from a single console in a
complete installation.
Note: A single console KVM switch can not be installed on a KH2508A/
KH2516A daisy chain.
Tables showing the relation between the number of computers and the number
of KH2508
A / KH2516A units needed to control them are provided on page 63.
To set up a daisy chained installation, do the following:
1. Use a daisy chain cable set to connect the Chain Out port of the parent
KH2508
A / KH2516A unit to the Chain In port of the child KH2508A /
KH2516
A unit (first station out to second station in, second station out to
third station in, etc.).
Note: 1. You cannot use the chain in port of the First Station, since it is the
highest level parent.
2. Daisy chain cable sets require a separate purchase. See your
dealer for details.
2. Cable up the computers and the switch according to the information
provided under Single Station Installation, page 14.
3. Repeat the above for any other switches you want to add to the chain.
4. Power up the installation according to the following procedure:
a) Plug in the power cord for the first station. Wait for the unit to ascertain
its station ID and display it on the Station ID LED. (The station ID for
the first stage unit is 01, the ID for the second stage unit is 02, the ID for
the third stage unit is 03, etc.)
b) Power on each station on the installation in turn (second station, then
third station, etc.). In each case, wait for the station ID to be ascertained
and displayed before powering on the next station.
c) After all the stations are up, power on the computers.
Note: A chained KVM switch with active console ports is not supported
since the channel is occupied by the master KVM switch.
